Steering system with lane keeping integration
First Claim
1. A method for steering a vehicle comprising:
- receiving a lane width value;
determining a keep out distance as a function of at least the lane width value;
receiving a vehicle width value;
receiving a vehicle center to left lane marker distance;
adding the vehicle center to left lane marker distance to the keep out distance and the vehicle width value;
receiving a vehicle center to right lane marker distance;
subtracting the keep out distance and the vehicle width value from the vehicle center to right lane marker distance resulting in a right value;
enabling a left warning responsive to determining that the left value is greater than zero and a left lane marker signal is available; and
enabling a right warning responsive to determining that the right value is less than zero and a right lane marker signal is available.

Abstract
A system for steering a vehicle including: an actuator disposed in a vehicle to apply torque to a steerable wheel; a driver input device receptive to driver commands for directing the vehicle; and a sensor for determining an intent of a driver and generating a signal indicative thereof. The system also includes: a lane keeping system for detecting a location of the vehicle relative to a lane marker and generating a lane position signal indicative thereof; a controller in operable communication with the actuator, the driver input device, the first sensor, and the lane keeping system. The controller provides a command to the actuator responsive to the intent of the driver, the lane position, and a desired lane position. The controller executes a lane keeping algorithm consisting of a single control loop based on at least one of the lane position and the lane position deviation.

10. A steering system for a vehicle comprising:
-
a sensor operative to detect a left lane marker and a right lane marker; a processor operative to; receive a lane width value; determine a keep out distance as a function of at least the lane width value; receive a vehicle width value; receive a vehicle center to left lane marker distance; add the vehicle center to left lane marker distance to the keep out distance and the vehicle width value; receive a vehicle center to right lane marker distance; subtract the keep out distance and the vehicle width value from the vehicle center to right lane marker distance resulting in a right value; enable a left warning responsive to determining that the left value is greater than zero and a left lane marker signal is available; and enable a right warning responsive to determining that the right value is less than zero and a right lane marker signal is available. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
